Geoarchaeology, Volume 41, Issue 1, January/February 2026.ABSTRACT Modern studies show that soil erosion results in a loss of ecosystem function, particularly fertility, and is a cause of declining agricultural yields. However, despite the well‐attested high rates of soil erosion across Roman and medieval Europe there appears to have been little or no soil‐associated decline in agricultural production—the ...

Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.Abstract Methane (CH4) emissions from freshwater ecosystems are significant but rarely quantified in vegetated zones. We assessed the influence of five macrophyte species that root in the sediment differing in growth form and root biomass on CH4 emissions and sediment gas storage.
